1 Claim.

This invention relates to a furrow opener, the general object of the invention being to provide a pair of disks arranged in tandem and so positioned that one disk will throw the soil to the right and the other to the left, with a bar connecting the two disks together and which is so formed that an intermediate part thereof can be readily attached to a beam of a plow, lister or other implements.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detaiLreference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is an elevation of the invention.

Figure 2 is a top plan view thereof.

In this drawing the letter A indicates a bar which is formed with the straight intermediate part I, the forwardly sloping part 2 terminating in 'a right angle part 3 and said bar also is provided with the rearwardly sloping part 4 terminating in aright angle extension 5. The extensions 3 and 5 are provided with holes for receiving the U-bolts 6 which hold the bearings or boxings I to the extensions 3 and 5. The spindle or journal of a front disk 8 is rotatably supported in the front boxing l and the spindle or journal of a rear disk 9 is rotatably supported in the rear boxing and each boxing is provided with a lubricating nipple ID for permitting lubricant to be placed in the boxing. The intermediate straight part I is fastened by one or more bolts II to the beam I2 with said part extending parallel to the length of the beam and the parts 3 and 5 are so arranged as to hold the disks one in front of the other and with the front disk set to throw the dirt to the left and the rear disk throwing the dirt to the right.

Thus this implement will make a complete furrow without the use of any other dirt removing means. The device is light in draft and can be used with other implements and wherever it is desired to form a furrow. I prefer to arrange the disks at approximately a degree angle with the beam l2.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim. 7

Having described the invention, what is claimed as new is:

A furrow opener of the class described comprising a beam having a downwardly extending rear part, a supporting 'bar having a straight intermediate portion connected with the lower portion of said downwardly extending part of the beam and said straight portion extending parallel to the length of the beam, the front portion of the bar sloping forwardly and outwardly in one direction andhaving a forwardly extending right angle part at its end, said right angle part being located to one side of the beam and extending toward the beam, the rear of the bar extending rearwardly and outwardly and having a right angle extension at its end, which extends outwardly from the plane of the opposite side of the beam, boxings connected to the right angle extensions, a front disk having a spindle part rotatably arranged in the front boxing with the spindle part connected to the convexed face of the disk, 2. rear disk having a spindle part extending from its concave face and rotatably ar-- ranged in the rear boxing, one disk being arranged in rear of the other and the front disk throwing the dirt to one side of the beam and the rear disk throwing the dirt to the opposite side of the beam.
